Patent GB-307858-A (GB)
Abstract: 307,858. Setright, H. R. Dec. 15, 1927. C o u n t i n g - apparatus.-The central registering mechanism of a totalizator comprises a series of indicating elements 32 driven from a source of power (belt-pulley 10) under the control of trains of escapements 46 electromagnetically released by the issuing-machines in the known manner. These escapements are shown as applied to the three lowest denominations and permit when actuated the rotation of shafts 33 each driven through a spring coupling 42 from a friction clutch 20 on a countershaft 19 geared with the power-shaft 12 to rotate at twice its speed. To provide for the reception of actuations at a faster rate than they can be registered, an accumulator gear is interposed and consists of a pair of worms 27, 34 driven respectively by the shafts 12 and 33 (the former through friction clutches 20) and gearing with a worm wheel 58 mounted on a slidabla sleeve 60. Normally this sleeve occupies the position shown in Fig. 4 whereby a flange 62 holds a bell-crank lever 66 in locking engagement with an escape wheel 64 on the shaft 26 of the worm 27 so that this cannot rotate. As impulses are received, however, the worm 34 traverses the sleeve 60 to the left thus releasing shaft 26 to permit drive from the power shaft 12 (through friction clutch 20 and bevel gears 31), to the indicator 32. If the actuations are too numerous and frequent the sleeve 60 eventually rocks a lever 72 and thus breaks the circuit of the issuing machines. The flexible coupling 42 consists of a spiral spring anchored respectively to discs rigid with the shaft 33 and the bevel wheel 39, and its purpose is to ensure immediate response of the shaft when released without waiting for the full effect from the friction clutch 20. To accommodate a large number of escapements in the units denomination these may be grouped as shown, one half the number controlling, through a 2 : 1 gear 57, a sleeve 52 differentially geared at 53 with the units shaft 33<1>. If as in Specification 307,818 a form of indicator is used not requiring a reduction from maximum to average load, the accumulator gears and shaft 12 may be omitted, the results then being indicated by numerals in the driven elements of the friction clutches 20 on the driving shaft 19. Specifications 233,702 and 269,998 also are referred to. Transfer-mechanism.-In one form, a singletoothed disc 78, Fig. 4, on the lower shaft 26 rocks a pawl to release an escape wheel on or differentially geared with the higher shaft. In another arrangement a contact operates the pawl electromagnetically.
Patent GB-280923-A (GB)
Title: Improvements in and relating to the production of sound records, applicable for use with motion picture machines
IPC: G11B7/00
Filed: 1927-11-16
Abstract: 280,923. Cortella, A. Nov. 16, 1926, [Convention date]. Optical apparatus and records; ribbon and like machines and records; records, duplicating; sound - reproducing apparatus associated with kinematography. - A sound-record applicable for use in association with a moving-picture film is made by recording the sound photographically upon a film by means of an oscillograph wherein a mirror is carried by a wire loop immersed in a damping liquid and connected in a microphone circuit, making from the negative so produced a positive on a sensitized strip of copper or the like, and preparing from the latter a master record from which duplicate records may be obtained by pressure. The sound-record may be formed on an edge of a picture film, or may be made on a separate film intended for synchronous working with the picture film during projection of the latter. Fig. 1 shows one method of making the negative sound record, and Fig. 2 shows part of the apparatus employed. A mirror 11 is mounted by means of wires 13 in a glass-walled cell 22 containing oil, Fig. 2, the mirror being placed between the poles of an electromagnet 17. A small fin 25 attached to the mirror increases the damping effect of the oil. The wires 13 are connected in circuit with a battery 16 and a microphone 15. Light from a source 7. reflected by a prism 10, falls on the mirror 11. which is vibrated in accordance with the current fluctuations set up by the sound-receiving microphone. The beam reflected from the mirror records the oscillations on a photographic film 1. From the negative film record, a positive is printed upon a strip of sensitized copper &c., which is then subjected to a bath of etching fluid, whereby the record trace is formed as a groove. From this strip, a master record, having the sound trace in relief is made in any suitable manner, and this record may be suitably reinforced, for example by electroplating. From it, impressions are made on a strip such as a picture film, sound-reproduction from the final record being effected by a sound-box having a stylus. The Specification as open to inspection under Sect. 91 (3) (a) comprises also the following subject-matter, which does not appear in the Specification as accepted. Fig. 1 (Cancelled) shows an apparatus employing a combined picture-film and sound-record. In this apparatus, which comprises a kinematograph projector 45 of ordinary construction. the sound-reproduction is effected by a microphone sound-box 40 controlling the loudspeaker 43. If the sound-record has been made on a separate film, the sound-reproducing machine is run synchronously with a kinematograph by directly coupling the machines together by chain and sprocket gearing. In a modified form of sound-recording apparatus, instead of an oscillograph having an oil-damped mirror, a device is used comprising a diaphragm which carries a rod supporting a slotted plate. This is placed in the path of a beam which acts on a photographic film.

IPC: G05B1/08
Filed: 1958-09-29
Abstract: 897,912. Automatic control systems. ROBERTSHAW - FULTON CONTROLS CO. Sept. 29, 1958 [Nov. 25, 1957], No. 31070/58. Drawings to Specification. Class 38 (4). Electrical error signals produced by deviations of a plurality of variables, such as pressure, thermocouple-detected temperature, position of a body &c., are applied through series impedances to the contacts of a rotary selector switch which successively applies them to a D.C. or chopper-fed A.C. amplifier. The amplifier output is applied through a further, synchronously-operated, selector switch to successively operate appropriate automatic correctors for the variables. At each control position of the selector switches an impedance connected between the contacts of the switches forms a feed-back path in shunt with the amplifier. At one position during each revolution of the selector switches the output of the amplifier may be fed back to its input to eliminate drift. Various arrangements of the series and shunt impedances to introduce integral and differential components of control are described. The period of rotation of the selector switches is made an odd multiple of half the period of the mains supply to reduce mains interference signal pick-up.

Title: Improvements in or relating to mechanism for removing cured tires from tire curing presses
IPC: B29D30/06
Filed: 1956-10-12
Abstract: 817,335. Removing tyres from tyre presses. McNEIL MACHINE & ENGINEERING CO. Oct. 12, 1956 [May 17, 1956], No. 31133/56. Class 87(2). A tyre T which has been moulded between a lower mould section 2 and an upper section 4 pivotally carried by rollers 8, 9 is raised out of the lower section by a diaphragm 15 and is then engaged by front and rear stripping arms. The front arm comprises a tube 20 fixed to rail section arms 22 which are guided to move in a desired path by a roller 32. The rear stripping arm comprises a tubular bar 75 connected to another tubular bar 76 by members 77 and two parallel arms 79 carrying a long roller 82 and another pair of arms carrying a roller 86. In operation, fluid pressure is supplied to a cylinder 100 to rock a shaft 62 causing a cable 50 to raise the front stripping arm and a cam slot 126 to raise the rear stripping arm. When the arms have reached the position shown in Fig. 3, a switch is operated to stop the movement of the arms to allow the diaphragm to drain and to return to its tyre receiving position. When the diaphragm reaches its lower position, it actuates a switch which causes the front stripper arm only to continue its upward movement to tilt the tyre until it slides over the rear stripping arm and along a take off conveyer 16. A switch is then operated to reverse the cylinder 100 and the arms return to the idle position. If the tyre sticks at the upper end of the conveyer 16, the roller 52 gives the tyre a kick on its return movement.

Filed: 1953-11-11
Abstract: 742,911. Friction brakes. OLYMPIA WERKE AKT.-GES., [formerly OLYMPIA WERKE WEST GES.]. Nov. 11, 1953, No. 31264/53. Class 103 (1). [Also in Group XIX] The driving motor of a calculating-machine is automatically switched-off at the conclusion of each working cycle and a mechanically-operated brake is then applied by the switch mechanism to bring it rapidly to rest. The motor 1 drives the machine shaft 30 through the usual onerevolution clutch 32 in a gear housing 2, and its spindle 5 carries a brake disc 3 engageable by a shoe 8. A tension spring 12 connects the shoe 8 to a switch lever 13, which is biased upwardly by a spring 17 but normally held down by engagement of a lug 23 under the tip 22 of a pawl 20, so pressing the shoe 8 against the brake disc 3 and releasing the motor contacts 15. When a motorized key is depressed to operate the machine, a lever 19 rocks counterclockwise and an arm 191 thereof trips the pawl 20 so that the lever 13 moves upwardly to the position shown in which its lug 23 engages the step 21 of the pawl; in this position of the lever 13 the shoe 8 is free to be disengaged by its spring 10, and the motor contacts 15 are closed. The arm 19<SP>1</SP> also releases the one-revolution clutch 32 so that the motor drive is transmitted to the machine shaft 30. The pawl 20 is carried by a lever 18 having a roller 27 bearing against a cam 29 on the shaft 30. As the shaft rotates, the lever 18 is rocked clockwise until, near the end of the revolution, the tip 22 of the pawl 20 engages once more over the lug 23 of the switch lever 13. As the revolution is completed the lever 18 moves rapidly counterclockwise at a drop in the cam and the tip 22 of the pawl 20 restores the switch lever downwardly, so opening the switch contacts 15 and applying the brake shoe 8. A rubber lining is interposed between the motor shaft 5 and brake disc 3 to obviate noise during braking.

Filed: 1963-08-10
Abstract: 1,027,352. Expanding wheel gear; linkwork. O. STIEBER. Aug. 10, 1963, No. 31659/63. Headings F2D and F2K. To maintain a substantially constant axial pressure between driving and driven flanges 4, 10; 6, 20 and an encircling friction ring 26 of an expanding wheel gear, the axially movable flanges 10, 20 are connected by a link 25 the effective length of which is automatically varied. The ends of the link 25 carry eccentrics 27, 31 pivoted at 28, 32 to the flanges 20, 10. Initial adjustment of the length of the link 25 and axial pressure is effected by rotation of the eccentric 27 which, thereafter, is locked by a setscrew 30. One way detents 35, 41 prevent anticlockwise rotation of the eccentric 31 relative to a lever 34 and the link 25. The end of the lever 34 engages between the arms 45, 46 of a U-shaped spring 43 so that on rightward movement of the flange 10 the lever 34 tends to rotate clockwise about the pivot 32 and thus tends to rotate the eccentric 31 clockwise relative to the link 25. The strength of the spring 43 is such that if the axial force is below a predetermined value the above clockwise rotation of the eccentric 31 is permitted to shorten the link 25 and increase the axial pressure. Ratio shift is effected by manual rotation of a pinion 18 engaging a rack 16 fast with the flange 10. A stop 38 limits angular movement of the lever 34.
